Trouble to turn ON

[Yuri2010]

Macbook13" (late 2008):
I change the keyboard (topcase)
and after turn on: screen - black, LED of key Numlock is green,
power LED blinks with triple sound...
Need advice.

Re-seat the memory. The topcase could be also bad. Are you replacing the topcase with the same type?
